What is this program? It was distributed with the LONG LONG AGO zip file
which contained the "Epic Megagames Sound System for Testing" beta thingy
(when Epic was still young).

It can be used to convert MOD, 669, STK, and S3M formats into the PSM format
used by One Must Fall: 2097. It can not, however, convert PSM files back
into mods/s3ms/etc. I am working on finding something like this right now.

Anyway, to use it, just type CONVERT. It will list the switches, etc.
It's pretty simple. To convert "COOLSTUFF.S3M" into a psm file, just type

    CONVERT /FE COOLSTUFF.S3M

And it will do the rest. (/FE is the flag for s3m's).

Anyway, happy creating!
